US and UK Tourist Visa Insurance Requirements Explained
Unlike the Schengen area, neither the US nor the UK legally requires proof of travel medical insurance to enter as a tourist — which surprises a lot of travelers, and leads some to skip it entirely. That's a mistake given the cost of healthcare in both countries.
United States
Whether entering on a B-2 tourist visa or via ESTA (Visa Waiver Program), the US does not require travel insurance as a condition of entry. What it does have: healthcare costs that are among the highest in the world, and no public system that covers visitors. A single emergency room visit without insurance can run into five figures. This is a "not required, but essential" situation.
United Kingdom
Standard Visitor visas similarly don't mandate travel insurance as an entry condition. Visitors are not covered by the NHS for most treatment (some emergency care is provided regardless, but is billed afterward for non-residents) — so the same logic applies: not legally required, financially necessary.
Where it IS checked at the border either way
Even where insurance isn't a visa requirement, border officers in both countries can and do ask about your ability to cover a medical emergency as part of general "sufficient means" questioning, particularly for longer stays. Carrying proof of coverage, even when not mandated, is a reasonable precaution during entry interviews.
The practical takeaway
Treat US and UK trips as needing the same medical coverage diligence as anywhere else — the absence of a legal requirement isn't a signal that coverage is optional, it just means no one will stop you at the border for skipping it. The hospital bill won't care either way.
